Description. Female.Length of idiosoma 370-380 Μm, width 340-350 Μm (n=3). Shape circular, posterior margin rounded, colour reddish brown.

Dorsal idiosoma ( Fig. 75 ). Marginal and dorsal shields fused. All setae on dorsal shield short (ca 19–21 Μm) and pilose, except setae j1 longer (ca 35–40 Μm). Surface of dorsal shield smooth, two groups of muscle scars situated on caudal part of the central region.

Ventral idiosoma ( Fig. 76 ). Sternal and ventral shields without sculptural pattern. Four pairs of sternal setae smooth and needle-like, St1 and St4 short (ca 8–9 Μm), St2 and St3 long (ca 23–24 Μm). St1 situated at level of anterior margin of genital shield, St2 at level of anterior margin of coxae III, St3 at level of anterior margin of coxae IV, St4 at level of central area of coxae IV. Three pairs of lyriform fissures situated on sternal shield, first pair situated near anterior margin of coxae II, second pair near St2, third pair at level of posterior margin of coxae IV. Ventral setae V2 (ca 10–11 Μm), inserted near basal edges of genital shield. One short (V7: ca 7-8 Μm) and needlelike, and one long (V8: ca 21-22 Μm) and needle-like setae inserted near caudal end of pedofossae IV. Pedofossae deep, their surface smooth, separated furrows for tarsi IV present. Setae ad smooth and needle-like (ca 11–12 Μm), situated lateral to anal opening. Stigmata situated between coxae II and III. Peritremes hook-shaped. Genital shield long and linguliform, surface without sculptural pattern. Base of tritosternum narrow, tritosternal laciniae smooth, subdivided into four branches ( Fig. 77 ).

Gnathosoma: Corniculi, internal malae, hypostomal setae, labrum, palp and epistome as in other Rotundabaloghia species. Fixed digit of chelicera without central tooth and with a finger-like apical process, internal sclerotised node present ( Fig. 78 ).
